What is a common reason for non-response to dietary therapy?

• A. Concurrent non-GI disease
• B. Poor owner compliance
• C. Disease requiring immunosuppressive therapy
• D. Incorrect diet

Answer: (D)

Non-response to dietary therapy almost always comes from not feeding the right diet. Dietary trials work only if the patient is on an appropriate elimination or hydrolyzed protein diet and nothing else is fed during the trial. If the diet chosen is unsuitable—wrong protein source, not truly allergen-free, or not an elimination/hydrolyzed option—or if there is cross-contamination or treats sneaking into the regimen, the gut continues to react and signs persist despite the trial. While other factors like concurrent non-GI disease, the need for immunosuppressive therapy, or owner noncompliance can influence outcomes, the most direct reason you’d see no response is that the diet being tested isn’t the correct one for that case.
